Operating Modes¶
Inputs and outputs, which are not used by the counters, are available for other tasks. In the following table, A means Input Channel A, B means Input Channel B and Z means Output Channel Z.
| Operating Mode | Function | Used inputs | Meaning |
|---|---|---|---|
| 0 | No counter | None | This operating mode is selected, if the integrated high-speed counter is not needed. |
| 1 | Up/Down counter (A) | A = Counting input | One Up/Down (dynamic changes) counter with set and reset input, end value reached indicator, touch/catch value and overflow flag. |
| 2 | Up/Down with release input (B) | A = Counting input B = Enable input |
One Up counter with enable input via terminal, counting is valid when input B is true. Dynamic Up/Down count possibility, end value reached indicator, Touch/catch value and Overflow flag |
| 3 | Up/Down counters (A,B) | A = Counting input 0 B = Counting input 1 |
2 counters with separate Up/Down and reset input |
| 4 | Up/Down (A, B on falling edges) | A = Counting input 0 B = Counting input 1 |
2 counters (counting on falling edge of input B) with separate Up/Down and reset input |
| 5 | Up/Down dynamic set (B) / rising edge | A = Counting input B = Dynamic set input |
One Up/Down counter with set and reset input, end value reached indicator, touch/catch value and overflow flag. Additional function to mode 1 is the dynamic set input (B) on rising edge of physical input. |
| 6 | Up/Down dynamic set (B) / falling edge | A = Counting input B = Dynamic set input |
One Up/Down counter with set and reset input, end value reached indicator, touch/catch value and overflow flag. Additional function to mode 1 is the dynamic set input (B) on falling edge of physical input. |
| 7 | Reserved | None | — |
| 8 | Up/Down with release (B), 0 cross detection | A = Counting input B = Enable input |
One 16 bit counter (in range of -32768 to 32767) with zero cross over detection, counting valid when input B is true |
| 9 | Reserved | None | — |
| 10 | Reserved | None | — |
| 11 | Incremental encoder | A = Trace A of the encoder B = Trace B of the encoder Z = Trace Z of the encoder (mechanical zero) |
One Up/Down counter for encoder x1 count, touch/catch value, RPI function, reset and set |
| 12 | Incremental encoder X2 | A = Trace A of the encoder B = Trace B of the encoder Z = Trace Z of the encoder (mechanical zero) |
One Up/Down counter for position sensor x2 count, touch/catch value, RPI function, reset and set |
| 13 | Incremental encoder X4 | A = Trace A of the encoder B = Trace B of the encoder Z = Trace Z of the encoder (mechanical zero) |
One Up/Down counter for position sensor x4 count, touch/catch value, RPI function, reset and set |
| 14 | SSI, absolute encoder | A = Data signal B = Clock signal |
Absolute positioning sensor using SSI interface |
| 15 | Time frequency meter | Z = Input signal | Time measurement of Z signal, rising edge, falling edge, rotation per minute and frequency calculation |
